Description

Technical Field

[0001] The present application relates to the field of lightning protection safety, and in particular to a lightning protection device. Background Art

[0002] Lightning is a natural phenomenon characterized by high voltage, large current, and strong electromagnetic radiation, posing serious hazards to buildings, equipment, and personnel. Lightning protection equipment primarily includes lightning rods, lightning strips, and lightning nets. These devices can direct lightning deep underground, preventing damage to buildings.

[0003] Lightning protection equipment includes a lightning induction part (lightning rod, lightning terminal), a conductive part (down conductor) and a grounding part (grounding body). The conductive part is mostly made of metal structures such as round steel or flat steel, and is laid openly along the outer wall of the building. In order to ensure low impedance, low cost and easy installation of the conductive part, the conductive part is usually exposed.

[0004] However, the part of the conductive part close to the ground is easily damaged, such as friction or impact caused by vehicles, humans, or animals, which may cause damage to the conductive part. Utility Model Content

[0005] The present application provides a lightning protection device for solving the problem that the portion of the conductive part close to the ground is easily damaged.

[0006] The present application provides a lightning protection device, which is used to be installed on a building. The lightning protection device includes a lightning receptor, a down conductor, a grounding body and a protective wall. The lightning receptor is arranged on the top of the building. The down conductor is laid on the side wall of the building, and one end of the down conductor is electrically connected to the lightning receptor. The grounding body is buried underground, and the other end of the down conductor is electrically connected to the grounding body. The protective wall is arranged outside the building, the protective wall is arranged on the ground, and the down conductor is partially arranged inside the protective wall. The protective wall is provided with a mounting hole, the down conductor passes through the mounting hole, and a gap is provided between the down conductor and the hole wall of the mounting hole. The height of the protective wall is 0.6m~2m.

[0007] The lightning rod, down conductor and grounding body in this application can play the role of attracting lightning and protecting buildings. The protective wall is installed outside the building, and the part of the down conductor located on the ground is set inside the protective wall. The down conductor can be protected by the protective wall to avoid the phenomenon of human or animal damage to the down conductor and reduce the possibility of damage to the part of the down conductor close to the ground.

[0008] In some embodiments of the present application, a gap is provided between the inner wall of the protective wall and the down conductor, with the gap between the inner wall of the protective wall and the down conductor being between 30 mm and 300 mm. This gap between the protective wall and the down conductor can prevent vibration during installation and use of the protective wall, or damage to the surface of the down conductor due to shaking of the down conductor itself.

[0009] In some embodiments of the present application, the spacing between the multiple inner walls of the protective wall and the down conductor is equal. This equal spacing between the multiple inner walls and the down conductor can ensure that the protective effects of the inner walls of the protective wall on the down conductor are similar, avoiding damage to the down conductor surface caused by too small a spacing on one side.

[0010] In some embodiments of the present application, a drain outlet is provided at the bottom of the protective wall, which can promptly drain rainwater or other accumulated water in the protective wall, thereby reducing water erosion of the down conductor.

[0011] In some embodiments of the present application, the protective wall is overlapped on the building. This can avoid conflicts between the down conductor and the protective wall during installation, ensure the original installation of the down conductor, and ensure a stable connection between the down conductor and the building.

[0012] In some embodiments of the present application, the drain outlet is arranged on a wall on a side of the protective wall adjacent to the building. The drain outlet is arranged on a wall close to the side of the building to avoid blockage caused by the drain outlet being conspicuous.

[0013] In some embodiments of the present application, the lightning protection device further includes a metal ring disposed within and fixed to the protective wall, the metal ring being sleeved over the down conductor, and spaced apart from the down conductor. The metal ring can absorb some of the voltage overflow from the down conductor during lightning conduction, thereby reducing the possibility of lightning on the down conductor being delayed in reaching the ground and causing danger.

[0014] In some embodiments of the present application, a plurality of metal rings are provided, and the plurality of metal rings are spaced apart along the axis of the down conductor. The plurality of metal rings can improve the ability to absorb current overflowing from the down conductor, further reducing the possibility of danger caused by lightning on the down conductor not being conducted underground in a timely manner.

[0015] In some embodiments of the present application, the lightning protection device further includes a grounding wire electrically connected to the metal ring and grounded. The grounding wire can transfer current on the metal ring to the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Lightning is a natural phenomenon characterized by high voltage, large current, and strong electromagnetic radiation, posing serious hazards to buildings, equipment, and personnel. Lightning protection equipment primarily includes lightning rods, lightning strips, and lightning nets. These devices can direct lightning deep underground, preventing damage to buildings.

[0025] Lightning protection equipment includes a lightning induction part (lightning rod, lightning terminal), a conductive part (down conductor) and a grounding part (grounding body). The conductive part is mostly made of metal structures such as round steel or flat steel, and is laid openly along the outer wall of the building. In order to ensure low impedance, low cost and easy installation of the conductive part, the conductive part is usually exposed.

[0026] However, the conductive part close to the ground is easily damaged, such as friction or impact caused by vehicles, humans, or animals, which may cause damage to the conductive part.

[0027] To do this, please refer to Figure 1 The present application provides a lightning protection device, which is used to be installed on a building 1. The lightning protection device includes a lightning receptor 2, a down conductor 3, a grounding body 4 and a protective wall 5.

[0028] Please refer to Figure 1 Lightning receptor 2 is installed on the top of building 1. Lightning receptors refer to lightning rods, lightning strips (wires), lightning nets, and metal roofs and metal structures that directly receive lightning strikes. When lightning strikes, lightning receptor 2 can quickly and effectively guide the lightning current to the down conductor 3. The lightning current is then safely discharged to the ground through the down conductor 3 and the grounding device, thereby protecting the safety of building 1, equipment, and personnel.

[0029] Please refer to Figure 1 Downconductor 3 is laid on the side wall of building 1, and one end of downconductor 3 is electrically connected to lightning receptor 2. Downconductor 3 is a metal conductor that connects lightning receptor 2 (such as a lightning rod) to the grounding device. Its main function is to safely conduct the lightning current received by lightning receptor 2 to the grounding device.

[0030] Please refer to Figure 1Down conductor 3 is typically made of metal materials such as round steel or flat steel, and is required to have excellent electrical conductivity and corrosion resistance to ensure stable conduction of lightning currents during long-term use. Down conductor 3 should be laid openly along the exterior wall of building 1 and grounded via the shortest possible path. It should be installed straight to avoid bending and breaking. The fixed spacing of down conductor 3 should comply with relevant regulations and generally should not exceed 1.5m to 2m to ensure that it will not loosen or fall off when subjected to external forces such as wind.

[0031] Please refer to Figure 1 The grounding body 4 is buried underground, and the other end of the down conductor 3 is electrically connected to the grounding body 4. The grounding body 4 is a collective term for the buried grounding body 4 and the grounding wire 7 connecting the grounding body 4 to the grounded portion of the electrical equipment. Its main function is to safely discharge the lightning current conducted by the down conductor 3 into the earth, thereby protecting the safety of the building 1, the equipment and personnel inside.

[0032] Please refer to Figure 1 The grounding body 4 can be divided into a natural grounding body 4 and an artificial grounding body 4. The artificial grounding body 4 is a metal conductor buried specifically for the purpose of grounding, such as galvanized angle steel, galvanized steel pipe, etc.; the artificial grounding body 4 can be designed and constructed as needed to meet different grounding resistance requirements. This scheme gives priority to the use of artificial grounding body 4.

[0033] Please refer to Figure 1 The protective wall 5 is provided outside the building 1 and on the ground, and the down conductor 3 is partially provided inside the protective wall 5. The protective wall 5 can be an arcuate wall or a square wall, and can be a masonry cement structure or a pure cement condensation structure. The protective wall 5 can be overlapped outside the building, and the protective wall 5 and the building can be bonded by cement or masonry overlap. An inner cavity can be formed inside the protective wall 5 to accommodate the down conductor 3.

[0034] Please refer to Figure 1 The protective wall 5 is provided with a mounting hole 51, through which the down conductor 3 passes, with a gap provided between the down conductor 3 and the wall of the mounting hole 51. The diameter of the mounting hole 51 should be larger than the diameter of the down conductor 3, and during installation, the distance between the down conductor 3 and the inner wall of the mounting hole 51 can be greater than 10 cm.

[0035] Please refer to Figure 1 The height of the protective wall 5 is 0.6m~2m. The height of the protective wall 5 determines the protected area and range, so the protective wall 5 can be 0.6m~2m high, and specifically can be any height of 0.6m, 1m, 1.2m, 1.5m, 1.8m, and 2m.

[0036] Please refer to Figure 1The lightning rod 2, down conductor 3, and grounding body 4 in the present application can play the role of receiving lightning and protecting buildings. The protective wall 5 is installed outside the building 1, and the part of the down conductor 3 located on the ground is set inside the protective wall 5. The down conductor 3 can be protected by the protective wall 5 to avoid the phenomenon of human or animal damage to the down conductor 3 and reduce the possibility of damage to the part of the down conductor 3 close to the ground.

[0037] Please refer to Figure 1 In some examples, a gap is provided between the inner wall of the protective wall 5 and the down conductor 3. The gap between the inner wall of the protective wall 5 and the down conductor 3 is between 30 mm and 300 mm. The gap between the protective wall 5 and the down conductor 3 can prevent vibration of the protective wall 5 during installation and use, or damage to the surface of the down conductor 3 due to shaking of the down conductor 3 itself.

[0038] In some examples, the gap between the inner wall of the protective wall 5 and the down conductor 3 can be any one of 30 mm, 60 mm, 80 mm, 100 mm, 150 mm, 200 mm, 250 mm, and 300 mm, preferably 150 mm.

[0039] Please refer to Figure 1 In some examples, the spacing between the multiple inner walls of the protective wall 5 and the down conductor 3 is equal. The equal spacing between the multiple inner walls and the down conductor 3 can ensure that the protective effects of the inner walls of the protective wall 5 on the down conductor 3 are similar, avoiding damage to the surface of the down conductor 3 caused by too small a spacing on one side.

[0040] Please refer to Figure 1 In some examples, a drain outlet 52 is provided at the bottom of the protective wall 5. The drain outlet 52 can promptly drain rainwater or other accumulated water in the protective wall 5, thereby reducing the erosion of the down conductor 3 by water.

[0041] In some examples, the drain hole 52 may be a square hole or a circular hole, and a plastic tube may be provided at the drain hole, or a conventional opening may be provided.

[0042] In some examples, the number of drain outlets 52 may be one or two.

[0043] Please refer to Figure 1 In some examples, the protective wall 5 is overlapped on the building 1. Overlapping the protective wall 5 on the building 1 can avoid conflicts between the down conductor 3 and the protective wall 5 during installation, allowing the original installation of the down conductor 3 to be complete and ensuring a stable connection between the down conductor 3 and the building 1.

[0044] Please refer to Figure 1In some examples, the drain outlet 52 is provided on a side of the wall of the protective wall 5 adjacent to the building 1. The drain outlet 52 is provided on a wall close to the side of the building 1 to avoid blockage caused by the drain outlet 52 being conspicuous.

[0045] Please refer to Figure 1 In some examples, the lightning protection device further includes a metal ring 6 , which is disposed within and fixed to the protective wall 5 . The metal ring 6 is sleeved over the down conductor 3 , and the metal ring 6 is spaced apart from the down conductor 3 . The metal ring 6 can absorb some of the voltage overflow from the down conductor 3 during lightning conduction, thereby reducing the possibility of lightning on the down conductor 3 being untimely transferred underground, which could cause a dangerous situation.

[0046] In some examples, the metal ring 6 can be an iron ring, or stainless steel or other materials. The diameter of the metal ring 6 can be smaller than the diameter of the down conductor 3. The metal ring 6 can be a circular ring, or an elliptical ring or other special shapes with connected ends.

[0047] Please refer to Figure 1 In some examples, multiple metal rings 6 are provided, and the multiple metal rings 6 are spaced apart along the axis of the down conductor 3. The multiple metal rings 6 can improve the ability to absorb current overflowing from the down conductor 3, further reducing the possibility of danger caused by lightning on the down conductor 3 not being conducted underground in a timely manner.

[0048] In some examples, the number of metal rings 6 can be set according to the height of the protective wall 5 , and the number can be set to 3 to 10.

[0049] In some examples, the bottom metal ring 6 may be installed in the soil to absorb part of the electrical energy appearing on the soil surface and avoid the formation of step voltage that may cause harm.

[0050] Please refer to Figure 1 In some examples, the metal ring 6 and the protective wall 5 can be snap-fitted or connected by bolts.

[0051] Please refer to Figure 1 In some examples, the lightning protection device further includes a grounding wire 7, which is electrically connected to the metal ring 6 and is grounded. The grounding wire 7 can transfer the current on the metal ring 6 to the ground.

[0052] In some examples, the grounding wire 7 can be a wire or a metal pole, and the grounding wire 7 is independent of the down conductor 3. The bottom of the grounding wire 7 extends into the soil and maintains a distance greater than 0.5m from the ground.

[0053] For example, a plurality of metal rings 6 may be connected simultaneously via the same grounding wire 7 , or a grounding wire 7 may be configured on each metal ring 6 .

[0054] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0055] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
